HAY-LOADER.

SPECIFICATION forming part of Letters Patent No. 336,948, dated March 2, 1856.

. Application tiled Apri! 25, i885. Serial No. 163,414. (No model.)

To all whom, it may concern.:

Be it known that l, Lewis H. RoBBiNs, a citizen of the United States, residing at McCool, in the county of Porter and State of Indiana, have invented certain new and use;

ful Improvements in Hay-Loaders; and I do declare the following to be a' full, clear, and l exactY description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings. and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to hay-loading machines; and it consists in the combination and arrangement of the several parts hereinafter described, and particularly pointed out in the claims.

ln the drawings, Figure l is a rear elevation, and Fig. 2 is a plan, of my complete machine. Fig. 3 is a detail plan of the driving mechanism. Figs. 4L and 5 are detail views showing the manner of attaching and removing the casters.v

For convenience of reference, I denominate that the inner7 end of the machine which carries the driving mechanism, and the opposite end, which carries the rake, the outer77 end.

A is a substantial frame, suitably constructed to carry all the parts oi' my invention.

a and a are two endless belts, arranged to run parallel with and sufficiently near each` other to carry the hay upward between them. These belts are arranged in the inclined position shown, having their upper ends supported at a suitable elevation to deliver the hay Onto the Wagon. The belts run on suitable rollers at their opposite ends.

On the end 0f the shaft of the upper roller of belt a a gear, a2, is fixed, and a gear, a, which meshes with gear a2, is fixed on the end of' the shalt of the upper roller of belt a. A small sprocket or other' suitable wheel, a4, is attached to t-he shaft next to the face of wheel A3, as shown. AnA additional carrier, B, is suitably hinged and provided With a belt, b, carried by suitable rollers, and driven by an endless chain passing over the sprocket-wheel a. This carrier turns on the shaft of sprocketwheel b. The sprocket-shaft is supported in bearings in brackets secured to the main framing. The carrier b is also supported on two arms, b'l b2, havingl their upper ends pivoted to the under side of said carrier, and having their lower ends pivoted on crank arms b" on a rock-shaitjourualed on the main frame, and operated by a connecting-rod, b4, and lever b5, arranged within and under the control of the driver, who can thereby raise or lower the outerI end of said carrier, as may be needed. The belts are driven by an endless chain, c, running over the sprockets al b and under one part or halt' of a double sprocket, c', on a shaft, hereinafter described. The tension of the chain c may be increased or di minished by the adjustable anti-friction roller c, jourualed ou a pin on the main frame.

d is the. main driving-wheel, to which is fixed the niaiu driving gear wheel d, which meshes with the driving-pinion d2. A clutch, di, is arranged ou the shaft of the pinion di, and it may be thrown into or out of gear by means of the pivoted rod d4 and a cranked rock-shaft, d5, which has its upper end eX- tended upward within reach of the driver.

d is a miter-gear fixed on the shaft of the driviugq'iinion, and it meshes with a miterpinion, di, on the shaft cA2 of the double sprocket c. Theshaft clextends from the rear side to the front side of theframe, and has fixed on its forward end a miter-pinion, C3, whichmeshes with a pinion, et, on a shalt, c5, which extends sidewise along the frame to a point about opposite the lower rollers, around which run the elevating-belts a ct, and has iixcd on its rear end the sprocket-wheel c6. An arm, e, pivoted concentrically with the sprocket c, is extended forward, and is furnished with a standard, e', in the upper end of which is a bearing for one ofthe gudgeons of the reel C. A double sprocket-wheel, e2, is journaled at the base of the standard, and another single sprocketwheel, e3, is arranged on the shaft of the reel at the top of said standard. Chains eA1 and e5 connect the sprocket-wheels o, e, and e3, and drive the reel. rlhe bracket or frame e e turns vertically on its pivot-point as the reel is raised or depressed, as hereinafter set forth. The standard e is pivoted by its lower end concentrically with the double sprocket e2, so

IOC

that it will always maintain a proper position relative to the reel-shaft as the latter may be raised or lowered. An endless-belt platform, D, is placed in the outer portion of the main framing, and is arranged to receive and deliver the hay to the elevating-belts a a. It is run by rollers driven by a sprocket-wheel, f, and endless chain f and the double sprocketwheel c.

The rake E is composed of a series of teeth, g, pivotally secured on a bar, g', arranged close to and at the front edge of the outer portion of the main frame, and so that they will pick up the hay from the ground and deliver it onto the endless beltD. The teeth are supported by a bail or rod, g2, journaled slightly in the rear of and lower than the rod g', so that the teeth will have the proper downward pitch. The bail is operated by a crankarm, g", vertically-disposed connecting-rod g, horizontal connecting-rod g5, bell-crank g, and lever gl, the latter being within reach of the driver. By this mechanism the pitch of the teeth is regulated at will.

Atilting reel-frame, F, composed ofthe arms h h' and rear bar, h, is provided to carry the reel. It is suitably supported in place upon journals so that it tilts easily. The rear bar, h, is arranged approximately in the same vertical plane with the rear side of the framing, and its arms are arranged at the ends of the receiving platform D and extend forward suiiciently far to support the reel in proper position over the rake. The reel is journaled in movable boxes h2, so that it may be adjusted along the arms as may be desired to bring the teeth nearer to or farther away from the receiving-platform. Ordinarily the reel is arranged with its shaftin a plane approximately vertical to the ends of the rake-teeth. If the grass is very heavy or is slightly damp, the reel is placed nearer the platform D, so that the fingers i will push the said grass onto the platform. Ihe pivoted standard e readily adjusts itself to the adjustment of the reeIshaft. The fram-e F is tilted by the arms k 7c', having their ends pivoted together and to the pitman k2. The arms k are also pivoted at their lower ends to the framing, while the upper ends of arms lc are pivoted to the rear bar ofthe tilting frame. I employ two sets of arms 7c k', connected by a coupler, 7c3. .This is done as a matter of preference; but a single set arranged at or near the middle on the bar h would give about as good results. The pitman k is connected by a bell.crank, k, and rod 705 with the operatinglever k6. By pushing the connected ends of the arms toward the outer ends of the machine they will extend and push the rear bar, h, upward, and thus lower the front ends of the arms h and let the reel down toward the rake, so that the teeth i will take deeper hold in the hay. By drawing the connected ends of these leversc k toward theinner end of the machine they will be contracted, and the frame F will be tilted, so as to raise the reel.

Instead of using the arms k lc and connecremoved and the weight of the machine rests on the driving-wheel dand the wheel I on the outer end of the machine. n

The casters are held by a hasp-fastening, as shown in Figs. 5 and 6, so that they can be easily removed or be put in position.

The weight of the tongue can be taken o" the horses by means of a lever, m, arranged within reach of the driver and suitably connected by rods fm. m5, connected by a rockshaft, m3, with astaple or hook, m, on the said tongue.

When the machine is notin use and is to be moved to another field, the casters are put in place and the tongue is tranferred to the inner end, as shown in Fig. 1.

The operation of my machinel will be fully understood by the description hereinbefore given. It does efiicient work, and is so compact in form as to beeasily handled. Its various operating-levers, gl, m, k6, and b5, have each the usual hand-operating latchV and a toothed segment engaged by the latch to lock them in their various adj usted positions. As this construction is common and well known, the operation of the parts will be readily understood.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-'- l. The combination, with the receiving-platform, a rake pivot-ed to its front edge, and an adj usting-lever connected therewith, of a tilting frame extending over the rake and supported by the platform, areel mounted ou the outer ends of the tilting frame directly above the rake, and a lever connected with the frame to adjust. it independent of the rake correspondingly with the position of the lat-ter, substantially as set forth.

2. The combination, with the endless belts a and a', gears al a3, sprocket-wheel a, carrierbelt b, supported upon rollers and having a driving-sprocket, b', of the shaft c, provided with -sprocket-wheel c', and gear dl, connected by intermediate gearing with the driving-v Wheel, the driving-chain c, and the interposed anti-friction tension-pulley, substantially as set forth.

In testimony whereof I aiix my signature in presence of two witnesses.
